[目的]为河北省区域试验提供后备品系。[方法]以郑单958为对照,通过对河北省农业科研单位提供的92个优良玉米杂交组合进行田间观察和产量测定,鉴定出综合表现较好的优良品系。[结果]抗性较好的品系有F6813、HD264、W6139、CH53、石低1、资5、HD395、石低3和唐98601;产量较高的品系有HD395、HD264、石低3、资5、F6813、唐98601、CH53。[结论]优势品系为F6813、HD264、资5、HD395、石低3和唐98601,建议明年参加区域试验,其他品系继续观察。
[Objective] To provide a reserve strain for the regional experiment in Hebei Province. [Method] With Zhengdan 958 as the control, 92 excellent maize hybrid combinations provided by agricultural research institutes of Hebei Province were observed and measured in field, and the fine lines with better overall performance were identified. [Result] The lines with higher resistance were F6813, HD264, W6139, CH53, low stone 1, high 5, high HD395, low stone 3 and high Tang 98601. The higher yield lines were HD395, HD264, , F6813, Don 98601, CH53. [Conclusion] The dominant lines were F6813, HD264, Zi5, HD395, Shi3 and Don98601. It is suggested to participate in the regional experiment next year, and the other lines should be observed continuously.
